Is the derivative of U(r)= a(r/b + b/r) U'(r)= a(1/br + br)? I know you have to do something with the rs... but that doesn't seem right. The multiple variables are really confusing.
Okay, I haven't really tried anything because as I said, the structure of the class is messed up. Most of the people in the class are seniors who already took a year of physics and calculus, but they randomly threw in people like me, who are in pre-calculus and haven't taken physics yet. Our...
